Yahoo! Updates its Sherpa Distributed Cloud Storage Platform

Yahoo! have blogged about the updates to its distributed
Cloud storage platform, Sherpa, over the past year.

Sherpa is horizontally scalable, and replicates data
asynchronously across data centres. The updates include the ‘YAK’
automated load balancer, which detects hotspots and moves shards to
lightly loaded servers, and support for Eventual Consistency,
meaning that applications can perform inserts and updates on a
table in the local replica, with low latency.

The blog also reveals that secondary indexes and record-level
adaptive replication, are also on the cards for Sherpa.
